Abstract: 1,133,094. Printing apparatus. HAREFIELD SERVICING CO. Ltd. 31 Dec., 1965 [2 Oct., 1964], No. 40318/64. Heading B6C. [Also in Division B2] The curved surfaces of cylindrical drums 11 are printed when rolled over a printing surface 5 by two overhead endless belts 9 when contact the top of each drum, one belt being adjacent each end. The surface 5 is inked by an inking roller 4 which moves in an endless path on chains 3, picking up the necessary ink from a pad 7 located beneath the lower flight 8 of the path. The pad is slidably removable from the apparatus for re-inking purposes. Two inking rollers may be provided if necessary. The apparatus is automatic in operation, limit switches being fitted to ensure that the surface 5 is re-inked after the printing of a drum. The electrical control circuit also includes provision for intermittent feed of the drums. In order to accommodate drums of different diameters the height of the belts 9 above the surface 5 is adjustable. In a modified apparatus one of the rollers over which the belts 9 pass is motorized. This eliminates the necessity for the separate motor 16 and belt drive which forms a feature of the embodiment of Fig. 1.

Title: Telemetering apparatus
IPC: H04B13/02
Filed: 1965-10-05
Abstract: 1,125,322. Electric selective signalling. E.G. & G. INTERNATIONAL Inc. 5 Oct., 1965 [26 Oct., 1964], No. 42201/65. Heading G4H. A telemetering device digitizes a plurality of analogue parameters and stores the digital results. A cable carries positive clock pulses some of which are larger to constitute reset pulses, to 8 underwater meters. In each meter an 8-stage binary control counter counts the clock pulses and is reset by the reset pulses. The readings of a magnetic compass indicating meter orientation, and a vane indicating water flow direction relative to the meter, are digitized by photo-electrically-sensed coded discs and set into a shift register. The contents of this register are passed as negative pulses to the cable between the clock pulses of a sequence of 32 clock pulses peculiar to the particular meter in response to a particular combination of states in the 3 highest order stages of the counter, these states being selected by switches. After the contents of the shift register have been thus passed out, new readings from the compass and vane are set in by flashing the lamps associated with the coding discs. Of the intervals between the 32 clock pulses, only 14 are used for the contents of the shift register, 16 of the others being used for two possible negative pulses from each of the 8 meters. These latter pulses come from a rotor at a rate proportional to water speed, are temporarily stored in a flip-flop, then inserted into the appropriate time slot under control of the 4 lowest order stages of the control counter, a particular combination of the states of the 3 highest order of these stages being selected for this purpose by switches ganged to the previously mentioned switches. A power supply in each meter is connected into circuit only as long as the clock pulse train is received. A radio link may replace the cable.
